Apparatus for burning petroleum



UNITED STATES PATENT OFFICEc APPARATUS FOR BURNING PETROLEUM.

Specification forming part ot' Letters Patent No. 48,967, dated July 25, 1865.

To all whom it may concern:

Be it known that I, E. MCKINNEY, of Middletown, in the county of Dauphin and lState of Pennsylvania, have invented a new and useful Improvement in Apparatus i'or Burning Petroleum; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming a part of this specification.

The drawing, containingonly one ligure, represents an apparatus by which I propose to illustrate my invention.

This invention consists in a new method of' generating heat by the burning of petroleum, and it is applicable to domestic and culinary purposes, to producing steam in boilers, and generally to every use where heat is required.

In the drawing I have shown a plan View ot' a steamboiler, A, and of a stove, B, each connected by suitable pipes to a tank, O, intended to contain petroleum, crude or refined, for the purpose ot' illustrating in the same view how my invention can be used either with a stove or a steam-boiler.

'Ihe furnace ofthe steam-boiler andthe tirechamber of the stove `are not seen in the drawing, but the pipes a and b are directed toward and are supposed to enter them.

C is a tank, of any suitable construction and size, for holding petroleum.

D isa cold-watertank, placed het Ween the furnace of the steam-boiler and the tank, through which the pipes b pass, and the object of which is to keep the pipes cool'and interceptany heat which may be radiated from the boiler and furnace. Any other suitable refrigeratin g medium may be used. Each pipe is provided with a stop-cock by which the iiow ot' the oil is regu lated.

The pipe a which conducts the oil to the stove B is not shown as passing through a re frigeratingmedium,for the reasons that a tank like D may not be necessary where the combustion takes place in a small furnace or stove in which a small degree of heat is generated, and that to show another tank would not be necessary to show my invention, because it would be only a duplication ofthe one placed between the tank G and the-boiler.

The pipes a b are introduced into the firechamber and furnace near or through their bot toms, and the said lire-chamber and furnace are supplied with air to support combustion, as in other irechambers, either through their doors or through their bottoms, by means of air-pipes or otherwise. The embouchures of said pipes a and b are covered with plumbago or other suitable refractory' material in a ine or pulverized state, so that the oil will be discharged into the same andA will saturate it. Dry clay will answer as a substitute for plumbago, and where a high heat is not desired sand will answer, but in that case the heat produced must not be high enough to vitrit'y it.

My invention is different from that patented to Mr. Dick, of Pennsylvania, inasmuch as he supplies hydrocarbon oils into a tire-box in such quantities as to rise above the level of the pumice-stone or other material which he places in the box, whereas I use plumbago or other refractory material in a pulver-ized or powdered state in sufficient quantity to cover and protect the delivery-pipes and their embouchures from contact with the lire and to cause the oil to saturate the mass and ditt'use the oil over and through it. I do not allow the oil to stand above the surface of the bed ot plumbago, but it is brought up to the surface by capillary attraction as the combustion proceeds.

This invention can also be applied to the production of light.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The method above described ot' generating heat and light from the combustion ot' petroleum or other hydrocarbon, crude or retned, by introducing it through pipes controlled by stop-cocks passing through any proper refrigerating medium to keep said pipes cool and prevent the transmission of the generated heat to the reservoir of oil into the place or places of combustion, and there mixing it with a refractory material pulverized, so that the pipes are protected from the tire, the oil being supplied in such quantity as merely to saturate the mass ot' material with which it is mixed, and being drawn to its surface by capillary attraction, substantially as above set forth.

EDMUND MCKINNEY.
